Charlie Sheen is making sure his trial on domestic violence charges doesn’t interfere with the taping of his TV show.

RadarOnline.com was in the Aspen courtroom Monday where Sheen entered his not guilty plea at the arraignment for his Christmas incident with wife Brooke Mueller.

And one of the more interesting things we overheard was when the trial date was being discussed. Pitkin County Chief District Attorney Arnold Mordkin told the judge he thought Sheen’s trial would last three days.

The first order of business in court was taking care of Charlie’s new lawyer. As RadarOnline.com exclusively reported Sunday, Los Angeles attorney Steve Cochran has now been hired to join the defense team. Cochran was in Aspen court Monday and filed a motion to represent Sheen.

Charlie’s representative Stan Rosenfeld made it clear that Charlie views the trial as a chance to set the record straight. Rosenfeld told RadarOnline.com: “Charlie is looking forward for this opportunity to clear his name.”

The judge said the Colorado Supreme Court, which handles such requests, has yet to respond. The judge then preliminarily approved Cochran as Sheen’s attorney.

And one bit of banter overheard by RadarOnline.com was telling: Sheen’s local attorney Richard Cummins and Mordkin were talking before the judge entered and were discussing trial dates. Cummins jokingly asked the prosecutor about his “parade of witnesses,” laughing as he said it. The implication was clear: Cummins believes the prosecutor has no witnesses.
